Assembly Notes

• As received from the 3D printer, the #2 screw holes will be slightly undersized. Use a hand drill and .067" bit to finish them out.


• Screwdriver side-access holes are provided for installing the printed circuit board.


• Optional: if you notice video blur due to camera vibration, make a pair of cork disks (40mm OD, 12mm ID, 3/32" thick), face them with waxed paper using rubber cement, and stack them between the camera bracket and servo, as shown above. Tighten the servo screw until all the play disappears, but not so tight that friction causes the servo to buzz or strain excessively.


• Cork sheeting can also be used as a pad under the feet of the unit, to further reduce vibration.
